My girlfriend and I are paleontologists, and we really love Jurassic Park.
On June 02, 2012, I surprised her with a secret trip to the fictional "Snakewater, Montana," which was the original filming location for the excavation scene at the beginning of Jurassic Park.
On a very windy day, I coaxed her into reenacting the "annoying kid" scene on camera, which was really the beginning of my proposal...she had no idea.
